Fields

m: usize

Maximum number of connections per node (except layer 0)

m_max0: usize

Maximum connections at layer 0 (typically 2*M)

ef_construction: usize

Size of dynamic candidate list during construction

ef_search: usize

Size of dynamic candidate list during search (can be adjusted)

ml: f64

Normalization factor for layer assignment (1/ln(M))

metric: DistanceMetric
